Sir i got an other problem i am calling all these statements in my button event handler like this

void analysis::on_pushButton_clicked()
{
 myplot * p = new myplot(gao.structpayloadgraph,gao1.structpayloadgraph, gao.structcol-2, "payload");
 
    myplot * p1 = new myplot(gao.structsessiongraph,gao.structsessiongraph ,gao.structcol-2, "session");
 
 
  QHBoxLayout * layout = new QHBoxLayout;
 ui->horizontalLayout_2->addLayout(layout);
 layout->addWidget(p);
 layout->addWidget(p1);
}

void analysis::on_pushButton_clicked()
{
 myplot * p = new myplot(gao.structpayloadgraph,gao1.structpayloadgraph, gao.structcol-2, "payload");

    myplot * p1 = new myplot(gao.structsessiongraph,gao.structsessiongraph ,gao.structcol-2, "session");

 
  QHBoxLayout * layout = new QHBoxLayout;
 ui->horizontalLayout_2->addLayout(layout);
 layout->addWidget(p);
 layout->addWidget(p1);
}

To copy to clipboard, switch view to plain text mode 

but the problem is that each time i click the button new graph appear and previous remains, like one !st click 2 appear on second they become 4 then 6......
how to i destroy QHBoxLayout in my button event handler

thanks

Add this in the beginning of the slot (i assume ui->horizontalLayout_2 does not have anything else, other than the layout you add)

void analysis::on_pushButton_clicked()
{
 QLayoutItem *child;
 while ((child = ui->horizontalLayout_2->takeAt(0)) != 0) {
     delete child;
 }
 
....
}

void analysis::on_pushButton_clicked()
{
 QLayoutItem *child;
 while ((child = ui->horizontalLayout_2->takeAt(0)) != 0) {
     delete child;
 }

....
}

To copy to clipboard, switch view to plain text mode
